Multi-Container B-Train Skeletal Combination
The Multi-Container B-Train Skeletal Combination is an ultra-heavy-duty, high-capacity intermodal transport system engineered specifically for high-volume freight corridors and multi-container logistics networks. Comprising a robust lead skeletal semi-trailer paired with a trailing chassis via a heavy-duty fifth-wheel dolly or direct B-train coupling system, it allows a single prime mover to haul multiple ISO containers simultaneously. Fabricated using high-tensile Q345B/Q550/T700 structural steel and automated submerged-arc welding, it features reinforced joint connections, precision ISO twist-locks, and multi-axle configurations (FUWA/BPW) designed to maximize payload tonnage and ton-mile efficiency. Fully certified under ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Ultra-Heavy B-Train Chassis & High-Tensile Structure
- High-Tensile Steel Construction: Fabricated using heavy-gauge Q345B, Q550, or T700 high-tensile structural steel plates, engineered with reinforced webs to handle compound torsional stresses across multi-trailer articulation points.
- Automated SAW Welding: Robotic Submerged-Arc Welding (SAW) combined with $CO_2$ gas-shielded welding guarantees absolute structural joint integrity under continuous multi-trailer hauling vibrations.
- B-Train Articulation & Dolly System: Features heavy-duty fifth-wheel dollies or integrated turntable connections that ensure smooth tracking, exceptional tracking stability, and minimal off-tracking in long vehicle combinations.
- Precision ISO Twist-Locks: Equipped with multiple sets of high-strength cast steel ISO twist-locks distributed across both lead and trailing frames to secure various container combinations securely.
2. Axle, Suspension & Pneumatic Braking Systems
- Multi-Axle Heavy-Duty Configuration: Configured with 4 to 6 axles total across the lead and trailing units (FUWA, BPW, or equivalent premium brands; 13T / 16T capacity per axle) optimized for heavy legal weight distribution.
- Suspension Options: Heavy-duty multi-leaf spring suspension or balanced air suspension systems designed to maintain uniform tire contact and stability across long road trains.
- Tire & Rim Setup: 16 to 24 commercial heavy-duty tires paired with high-load steel rims.
- Synchronized Pneumatic Braking System: Advanced multi-line pneumatic braking system featuring high-capacity emergency relay valves, quick-release valves, and full ABS compliance ensuring synchronized, powerful stopping capability across the entire train length.
3. Operational Accessories & Logistics Setup
- Landing Gear & Kingpin: 28-Ton two-speed heavy landing gear on both units and standard 50# (2") or 90# (3.5") interchangeable kingpins for secure tractor and dolly coupling.
- Electrical & Lighting System: Multi-trailer 24V 7-pin LED lighting system with waterproof connectors, jumper cables, and rear warning markers meeting international road safety directives.
- Standard Utility Add-ons: Multiple spare tire carriers, steel mudguards with anti-spray flaps, and large lockable tool boxes on each chassis unit.
Commercial & Logistics Terms
- Warranty Policy: 3-Year warranty for main beams and articulation coupling structures; 1-Year warranty for axles, suspension, and braking components.
- Delivery Lead Time: 35 – 45 working days upon order confirmation.
- Packaging & Shipping: Nude packing; shipped in modular sections via Ro-Ro vessel, Bulk Cargo ship, or specialized flat-rack containers.
- Payment Terms: T/T (Telegraphic Transfer), L/C (Letter of Credit).
